DAMPER.

Application filed February 8, 1916.

To all whom it may concern:

Be it known that we, GEORGE V. Gunny, a citizen of the United States, and a resident of Amityville, Suffolk county, New York, and RICHARD Rouse, Jr a citizen of the United States, and a resident of Newark, EsseX county, New Jersey, have invented a new and useful Improvement in Dampers, of which the following is a full, clear, and exact description.

Our invention relates to improvements in dampers for the pipes of stoves, furnaces, and the like.

Our invention is more especially applicable to the pipes of heating furnaces, although it can be used in connection with any smoke pipe. It has come to be a frequent practice to have thermostatic or other regulators for furnace dampers so that the dampers in the pipe and below the grate are automatically regulated.

Our invention is intended to meet this new condition, and produce a damper which can be readily applied to the smoke pipe of a furnace, which will close by gravity, and which has a weighted lever member connected with the pintle or pivot of the damper in such a way that it can be adjusted so as to cause the damper to close by gravity without reference to the position of the pipe. The ar rangement is such that this lever member can also be mounted in such a way as to make the damper operate very easily.

Another object of our invention is to construct the pintle of the damper and the lever member attached to it so that the direction of the lever with relation to the pintle can be reversed or changed very easily and with very little adjusting.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar reference characters indicate corresponding parts in all the views. 7

Figure 1 is a detail front elevation of the damper and its connected lever member, the parts being shown before being placed in position in a pipe. Fig. 2 is an edge view of the structure shown in Fig. 1. Fig. 3 is a view similar to Fig. 1 but with the lever member reversed. Fig. 4: is a broken detail front elevation of the damper, its pintle, and the plate on the pintle, the lever member be- Specification of Letters Patent.

ing removed. Fig. 5 is a broken detail edge new of one end of the lever member, and Fig. 6 is a side elevation of a furnace fitted with dampers showing my improvements.

In the drawings 10 represents a conventional furnace which is fitted with a pipe 11, and the pipe is shown provided with dampers 12 and 12 while the front lower part of the furnace has the customary damper 1 The dampers in the pipe and at the front are connected by a chain or cable 15 which runs over the guide pulleys 16, and has a branch 17 connected with the damper 12, while the main cable connects with the damper 12. It will be seen that the cable 15 can be connect ed with any usual thermostatic or other motor so as to be operated from a distance. Vhen the damper 1 1 closes, the damper-'12 or 12 as the case may be, opens, and when the damper 14 opens, the pipe dampers close. Obviously there can be oneor more dampers in the pipe, and these can be arranged in any preferred way. There is nothing novel about the arrangement above referred to, butour invention lies in the detail construction of the damper which adapts it to meet the conditions above described.

The damper 12 is provided with a pintle 19 to which the damper is rigidly secured, and this can be pivoted in the frame 18 in the usual or any preferred manner, while the frame 18 is fastened to the pipe in the usual way. At its outer end which in practice projects from the pipe, the pintle 19 merges into a flat plate 20 which traverses the outer end of the pintle at right angles, and is provided with holes 21 and 22, these being preferably screw threaded. The plate 20 lies in the same plane as the damper 12, and it will be seen that it is therefore a simple matter to cast the damper 12, pintle 19 and plate 20 in one casting. This makes a very cheap and permanent construction.

The damper is provided with a lever member 23 which is recessed at one end as shown at 23*, so that the recessed part substantially corresponds to the size of the plate 20. The recessed part of the lever member is also provided with a transverse pin 24 which is adapted to slip into either of the holes 21 or 22. The recessed part of the lever member is also perforated as shown at 24, so that this perforation shall aline with one of the aforesaid holes 21 or 22- when the lever member 23 is in position. The lever member 23 is provided with bosses 26 to which connection can be made with a wire, cable, or the like, and has an oifset free end 27 which is preferably perforated as shown at 28 to facilitate connecting with an operating cable.

The weight of the lever 23 is sufficient to 7 close the damper 12 when the damper is properly balanced, and it will be seen that the construction which we have set forth enables the lever member to be attached to the pintle of the damper so that the. lever member will always be in a position to cause its'weight to effect a closure of the damper by gravity. To effect this adjustment it is only necessary to attach the lever member to the plate 'so that it will extend in a desired direction, and it will be seen that the attachment and adjustment is of the simplest nature. By placing the pin 24- in the hole 21 and bringing the recessed part 23 of the lever and the plate 20 together,

a screw 25 can then be inserted through the holes 22 and 245 and the lever will extend in one direction and be rigid on the plate 20; while by placing the pin 24 in the hole 22 and the screw 25 in the holes 21 and 24 the lever member will extend in exactly the opposite direction, and it will be seen that there can be still further adjustment made because the lever member can be applied not only to either end, but to either side or face of the plate 20. Thus it isthe simplest matter tochange the direction and the tension of the lever 23 with relation to the pintle l9 and damper 12, and the parts are held together by a single screw.

We claim: 7

1. A damper of the kind described having a fixed pintle, a plate on the pintle extending at an angle thereto, a detachable lever adapted to extend from either end of the plate having a seat to fit the top and at least one end of the plate, and means for fastening the lever to the plate.

2. The combination with a smoke pipe having an opening through the wall thereof, a pivoted damper adapted to close said opening, a flat plate rigid onthe pintle of the damper and with its flatsurface in es-' sentially the same plane as the'damper, and a weighted lever having means for attachment to the flat plate, and a shoulder adapted to fit either end of said flat plate.

3. A damper having a fixed pintle, a plate rigid on the pintle, a weighted leverhaving one end recessed to fit against the plate and overlap one end thereof, and

means for attaching the plate and lever toon the pintle, and a weighted lever 11c ving a pin thereon to fit one of the perforations of the said plates, and a shoulder adapted to abut with either end of the plate, said lever beingshaped to fit snugly 'againstthe plate. s p

6. A damper of the kind described having a fixed pintle, a perforated plate on the pintle, and a weighted lever shaped to lie against the face of the plate and to abut with one end thereof, said lever having a pin to enter one of the perforations of the aforesaid plate, and a hole in i'tradapted to register with one of the aforesaid plate holes. 7 Y
